To (all when b it by concern.-

Be it known that I, .Fnunnuro F. Snrrr, a. citizen of the United Stntes,residing in the city of St. Louis, in the State of Missouri, haveinventedv certain new and useful linpi'oveinents in Electrical Witter-dlceters, of which the following is it full, clear, and exactdescription, reference being had to the occonipenying drawings, formingparto'l this specification.

My invention relates to on electrical water-heater designed to he piecedin n receptocie in writer to be heated and, briefly stated, it comprisesa plurality of insulator heat-i .1- dinting sections and n. heating-coilwound throughout the series of snidfsections in o contii'iuous circuit,so that said hent-rndiut- T ing insulator-sections Will serve asdill'usion members for the herd. irnpn d thereto from the coii, whilenntintiiining tire coil throughout its extent inn sepnrs nrdi tiou.

notch it one end of the second section, and laid in the longitudinalgroove at the top side of said second section. The next section 1 isthen hiid upon the second section and the wire laid into its groove ntthe upper side in the some manner :13 just described in com ner'lionwith the second section. This pro cedure is continued until the coil islaid throughout the series of sections made use of It will be seen thatby folding the coil at each end of its series of folds in the notches 3of the sections 1 all the coil folds are positioned inwardly from theends of the sections, thereby providing (or the jutting ends ol -thesections, the sides of their notches serving as insulotors to preventconinct of metal or any other conductor of eierli'ir-itv with said coil,

the coil folds'with such conductor. the hunter hos been completed, theterminals of the (oil are connected to any suitable sourre ol supply ofelectricity. During the use oi" the heater the sections 1, being ofinsulating material nnd good conductors of heat, readily receive horncoinnrunirnted thereto from the coil l and. rndiiuo such hen-t therefrominto the receptacle in which the heater is located in the order, with nresult that the. water is rapid 1 hosted.

In the inodilirntion illustrated in Figs. IV to Vi, inclusive, idesignates a. core which is provided with u. cireinnl erentinl groove 1and contains 21 bore 1". 1 represents 21 scries ol herd-radial inginsulntonscgnicnts each oi which is providei'l interiorly and exteriorlywith grooves 2". is the electrical conductor-coil. in building up thismodified form of heater .l lirst introduce one terminal of the wire. oiwhich the conductor-coil made through the bore l in thecore l and permitsaid end oi the wire to project from said bore through the center ofsaid core to serve'os one ol'the terminals oi the coil. I then. wind thecoil-wire inl'o illti' groove of Said cole'and phne against said woundportion of the wire rind ogninst the core one oi the segments 1 itiltlsnot-her segment against snid core to pposc said tirst-phiced segment. Aportion of tho wire is thus inclosed between the core end the lirst-l lsegment, and the wire is then hent outwnr end its course continued When, 0nd segments.

1. In an electrical Water-heater, the combination of a plurality oiheat-radiating sections that are a non-conduotor'of electricity, and anelectrical conductor-coil wound throu hout said sections; said sectionsbeing rovid ed With notches at their ends in which the folds of saidcoil are located, substantially as set forth.

2. In an electrical Water-heater, the combination of a plurality ofheat-radiating sections that are DOiL-COIldUCtOTS of electricitv andeach of which is provided with longitudinal grooves at its sides andnotches at its ends, and an electrical conductor-coil laid in saidgrooves and notches throughout the series of said sections,substantially as set forth.
